A 109-year-old superfan of the Baltimore Orioles threw out the team’s first pitch for Opening Day on Thursday.

Arthur Green, a veteran who served in two wars, has been a witness to the entirety of the O’s modern history — since the team was relocated from St. Louis to Baltimore in 1954, according to MLB.com. Green was in his late 30s at the time, and had already served time in both wars.

This wasn’t Green’s first time on the mound. He threw a pitch in August 2023, when he was 106. At the time, Green’s daughter, Myra, told WMAR 2 News Baltimore that was the “happiest day of his life.”

In December, Green was named the Orioles’ 2026 Mo Gaba Fan of the Year — a fan who gets to serve as the team’s unofficial “10th man” at each season’s home opener, MLB.com reported.

The Orioles went on to win the season-opening game — perhaps thanks to Green’s pitch — 2-1 over the Minnesota Twins.
